The sizing for XS and S are the same on the original geo chart photo?

So this frame has caught my eye and I noticed that geometry-wise it's basically a 3T Racemax 2 Italia, the difference is no more than a few mm's here and there. Just an observation.

Well this looks very very interesting... I have a full spreadsheet built up for the LCR018-D and was just getting ready to pull the trigger - but 50 mm clearance really speaks to me. Anyone got an idea if you'll be able to order the forks with mounting points?  ;D I would ask Wendy but I think she's getting somewhat tired of my questions at this point  ::)

Also tack viktor for the render - helps to visualize. Those huge tires with brown sidewalls look so good...

This seems like such an interesting frame to me because it's within single-digit millimeters of stack/reach of the LCR018-D, just with clearance for 50C tires. I'm wondering why someone would ever opt for the LCR018 when this one is nearly identical unless 1) whatever marginal weight savings really, really matter to you, or 2) you truly never plan to run tires wider than 35C or so... in which case why not look at a frame with even less tire clearance to maximize aero benefits?

As of right now, seems like this is the ideal N=1 bike for me...

Yeah full agree. I was honestly quite fine with 38c because I was mostly planning on riding on paved roads and quite nice gravel roads (plenty of those in southern Sweden). But if I can buy pretty much the same bike but ALSO have the possibility to send it down some gnarlier stuff with huge tires... I mean it's a pretty easy call.

As an aside - don't know if I'm fooling myself but I swear the fork looks different than LCR018-D, cooler somehow (from the side).

Anyways, how are you planning on building it up?

Same here. 38C would get the job done for 99% of my riding around the New York City area.  A vast majority of my rides would be on our (relatively crappy) city streets, so ~35C tires would be ideal. Nearly all of the gravel around NYC would be fine on 38Cs with some tread. But there are a few routes a bit farther afield that would benefit from 45Cs, and I would hate to exclude myself from those rides if I don't have to. My current bike is an aluminum gravel bike (GT Grade Comp), so I can access those trails, but the geometry is so long and slack that it feels a bit like steering a boat on the road. This LCG072 seems to make no trade-offs in terms of geometry that would affect me on the vast majority of the courses I ride. Pretty compelling.

Anyway, I've already got two wheelsets... one Elitewheels Drive (gen 1) 50D running Conti GP5K 32C for road duty and one Elitewheels Marvel G35 running Pirelli Cinturato Gravel H 45C for gravel duty. Idea would be to build this frame up with a GRX 2x12 Di2 groupset, british racing green custom paint, with brown saddle & bar tape. I've always lusted after that color combo.

Also re: the fork, yeah I think it's a new design. I started a thread about this on the Chinese Carbon subreddit and someone mentioned that Lightcarbon did redesign the fork for even more clearance, but that's unverified info since few details about this frameset exist in the real world.

How would you build this one up?

Would you go full GRX or since it's made for a lot of road (thus 2x) you would put a 105 (or other) fd + crankset ?

Maybe I just haven’t done enough research but it seems to me that there’s no real downside to a full GRX groupset on the road. It’s marginally heavier, though to make up for that difference I’d just make sure I pee before heading out  ;D.  On the other side, the FD affords more rear tire clearance, the RD gives you a clutch to prevent dropped chains on rough terrain (including cobblestones and potholes), and the hoods have superior ergonomics to 105 (imo). Maybe there’s something I’m missing but I figure I’d keep it simple and just go full GRX.

I was inquiring about the LCR72 frameset when Jim sent me this video link. Uploading it here to see if you guys are able to discover anything new from this walk around video.

Thanks for sharing the video. 50c tires? Seems like there is no room for more…!!
Looks gorgeous

Now we gotta sort out the Gravel Handlebars thing: Wendy apparently says 36cm minimum while Carol told me 38cm minimum…
I have & ride 23 bikes
Also I ride a lot, like a lot lot

According to Jim, rear tire clearance measures (WAM) are 50mm for 1x and 45mm with FD/2x...

Fork can not be delivered with mounting points. I asked for my 56cm. Only the toptube can have 2 mounting points

I ordered a 56 end of May and made a down payment to reserve a production slot. Then created a design which is now finished and made the balance payment.
Frame comes in at 719 usd, custom painting is 250usd. That is the price for most paint jobs. New policy from LC. Even a matte black with decals costs 250 usd. So you might just as well go crazy and have it in a color with custom decals.

I only have to decide if I'm going for the HBR18 bar or the new HBR20. Can't do that right now as the HBR20 specs are not yet final.

Hopefully my frame will be ready end of this year.
